End Support WBD

page as pdf

Group: 1356

Application

In combination with a channel, End Support WBD is particularly suitable

• for setting up support structures attached to walls, floors and ceilings and in particular
• as a base for frame structures made of Sikla channels.

The generous dimensions and the rhomib shape of the mounting plate provide for a high bending moment and safely stabilise lateral loads.

Installation

Normally, two bolts grouped opposite to each other and along the load axis are sufficient. Only in exceptional cases (e.g. high props in frameworks) four bolts are required.

Minimum torque values for the hexagon bolts of the 41 Holding Brackets are:

Types	Holding Brackets [pcs]	Bolt for Holding Bracket	Accessories	Torque [Nm]
41/21-31 up to 41/41-45	1	M10	pre-assembled	40
41/52 up to 41-75/75	2	M12	pre-assembled	60
41/21 D up to 41/45 D	1	M10	in loose form	40
41/52 D up to 41-75/75 D	1	M12	in loose form	60

For ceiling mounting under high loads (up to 7.0 kN), we recommend the use of at least one fully traversing bolt for connecting the channel to the End Support WBD (for examples see "Installation Guideline").

Working load for Wall mounting:
See tables on the following pages. The figures apply on walls if two bolts of the load class as stated are used.

Working load for Ceiling Mounting:
The permissible maximum vertical load for ceiling mounting structures fixed by way of at least one traversing bolt (class 8.8) amounts to 7.0 kN

For End Supports WBD for single channels, the following values apply subject to the condition that all included accessories are assembled correctly.

Types	Working load (tension) for ceiling mounting [kN]
41/21-31 up to 41/41-45	2.0
41/52 up to 41-75/75	4.0

Material

Steel, cold-formed, electro-galvanised
